On 13 July 2018, King Willem-Alexander, Queen Maxima, Princess Catharina-Amalia, Princess Alexia, and Princess Ariane posed for a summer photo session at Villa Eikenhorst, their residence in Wassenaar.

The summer photo session takes place each summer so that the family can have privacy during the rest of their summer holidays. This was the last photo session to take place at Villa Eikenhorst as the family moved to the newly renovated Huis Ten Bosch Palace last year.

Queen Maxima wore a denim shirt dress by CO with nude wedges. Her gold necklace and her gold bracelet were by Argentinian designer Aracano.

Princess Catharina-Amalia wore a floral printed midi dress by Dutch label Sissy-Boy.

Princess Alexia wore a floral printed dress by Sandro with white Superga platform sneakers while Princess Ariane wore a red striped dress with a white denim jacket.
